Currency Converter with Fees — What You Actually Receive
Most converters show the mid-market rate — the rate nobody actually gets. Enter the rate you looked up plus the margin and fee your bank or transfer app charges, and this shows what will really land in the other account, your effective rate, and exactly what the conversion cost.

How this calculation works
The mid-market rate is the midpoint between the buy and sell prices on the global currency market. It is the rate quoted by search engines and financial sites, and it is the honest reference point — but it is not a rate you can transact at.
Providers make money in two places. A margin (spread) is a percentage quietly subtracted from the mid-market rate, so a 1.5% margin on a 1.10 rate gives you 1.0835. A fixed fee is charged in the currency you send, so it never gets exchanged at all.
Because a fixed fee is deducted before the exchange, this calculator applies it first: received = (amount − fee) × rate × (1 − margin ÷ 100). That ordering matches how transfers are actually processed.
Total cost is measured against the mid-market benchmark in the target currency: what you would have received at the pure mid-market rate, minus what you actually receive. The cost percentage makes providers comparable regardless of amount.
Worked example
You send 1,000 USD to the eurozone with the mid-market rate at 1.10. A bank quoting "no fees" but taking a 2.5% margin gives you 1.0725, so 1,072.50 EUR arrives — the mid-market amount was 1,100.00, so the conversion cost 27.50 EUR, or 2.5%. A transfer app charging a 0.4% margin plus a 4 USD fee delivers (1,000 − 4) × 1.10 × 0.996 = 1,091.22 EUR, costing 8.78 EUR or 0.8%. Same headline "rate", three times the difference.
Mid-market rate disclaimer — read this first
This calculator does not fetch or store exchange rates. The rate is whatever you type in, which is a design choice rather than a limitation: a converter with a cached rate looks authoritative while quietly being hours or days out of date, and currency markets move continuously.
The mid-market rate you look up is a reference, not an offer. It is the midpoint of interbank buy and sell prices, available to no retail customer. Treat every number here as an estimate for comparison and planning — for a real transaction, use the exact rate and fee schedule your provider confirms in writing at the moment of execution, and remember that rates quoted outside market hours may not hold when markets reopen.
Where the cost actually hides
The headline "fee" is rarely where the money goes. Comparing providers on the same 1,000 conversion at a 1.10 mid-market rate makes the pattern obvious.

How to compare two quotes in ten seconds
Ignore the marketing entirely and ask one question of each provider: how many units of the target currency will be credited to the recipient? That single number already contains every margin, fee and deduction, and it is the only figure that is directly comparable. Run each answer through this calculator to see the cost as a percentage, and the cheaper option is unambiguous.
Two things worth checking beyond the number. First, whether the rate is locked and for how long — an unlocked rate can drift before your transfer executes. Second, whether the recipient's bank charges an inbound fee, which no sending provider will mention. For recurring transfers such as salary, tuition, or mortgage payments abroad, a 2% margin difference compounds into a meaningful annual sum, so it is worth the one-off effort of comparing properly.
Frequently asked questions
Does this calculator use live exchange rates?
No, deliberately. You enter the rate, which means the result is never based on a silently stale cached number. Look up the current mid-market rate on your search engine or a market data site, paste it in, and the comparison stays accurate for the moment you are actually transacting.
What is the mid-market rate?
It is the midpoint between the buy and sell prices for a currency pair on the interbank market — the rate you see on Google, Reuters, or XE. No retail customer transacts at it, because every provider adds a margin. It matters as the neutral benchmark: comparing what you receive against the mid-market amount is the only way to see a provider's true cost.
How do I find the margin my bank is charging?
Ask for the exact rate they will apply, then compare it to the mid-market rate: margin = (mid-market − their rate) ÷ mid-market × 100. If they quote 1.0725 while the market is at 1.10, the margin is 2.27%. Providers advertising "zero commission" or "no fees" almost always earn from this spread instead.
Is a fixed fee or a percentage margin cheaper?
It depends entirely on size. A flat 5 fee on 100 is 5%; on 10,000 it is 0.05%. A percentage margin costs the same proportion at every amount. So a fixed-fee provider with a thin margin usually wins on large transfers, while a low- or no-fee provider can win on small ones. The cost percentage output is there to settle it for your specific amount.
Why does the amount that arrives differ from what my provider quoted?
Three usual causes. Intermediary correspondent banks can deduct their own charges mid-route on SWIFT transfers. The receiving bank may levy an inbound fee. And the rate can move between quote and execution unless it was locked. This is also why a quoted rate with a stated expiry is worth more than a slightly better unlocked one.
What about card payments abroad?
The same maths applies, with two extra traps. A foreign transaction fee (often 1–3%) sits on top of the network's rate, and "dynamic currency conversion" — the terminal offering to charge you in your home currency — typically embeds a margin far worse than your card's. Enter the DCC rate as your rate and its true cost becomes visible immediately.
Does the calculator store the amounts I enter?
No. Everything runs in your browser and nothing is uploaded, logged, or saved.
Should I convert now or wait for a better rate?
That is a forecasting question this tool cannot answer, and short-term currency movements are famously unpredictable. What is knowable and controllable is the cost you pay to convert. Cutting a 2.5% margin to 0.5% is a guaranteed saving; waiting for a 2% favourable move is a bet.
